One ofV thewobjeets of my invention 1s to provide a support forattachment to a metal window sash having a transversely concavedVvertically extending surface on its outer edge adjacent the portion tobe embedded in a concrete post.

Another object of my invention is coprovide such a support in which theheaded projections over which the clips s lide 'are provided withshoulders intermediate the head and base for spacing the clip outwardlyto prevent its engagement with either the window or other adjacentparts.

Still further objects of the invention are to provide a sturdy, rigidattachment member which will be efficient in operation and not liable tobreakage.

Still other and further objects will become apparent to those skilled inthe art from a consideration of the following description and drawing,wherein Figure 1 is a front elevation of a window sash showing myimproved support in osition,

i 2 is a horizontal sectional view on the llne 2-2 of Fig. 1, showing awindow washers clip attached to the support, and

Fig. 3 is a vertical sectional view on the line 3 3 of Fig, 2.

Considerable dilficulty has been found in providing a support forengagement by a window washers harness at the point of juncture betweena metal window sash and concrete wall or post, where the edge of thesash is embedded in the concrete. This is particularly true of the metalwindow frames known as fenestra, wherein a Very small amount of metal isexposed between the concrete wall and glass window.

The vertical strip of metal forming a portion of the outer side of thewindow sash has a transversely concaved surface adjacent the glass and Ihave so arranged my improved support as to permit its attachment to thissurface and yet space the Yspeisernen of Letters Patent.

Yclip outwardly away from the included anle between the glass andconcrete. accomplish by providing the base from which the clip engaginglug extends. with a transversely convex surface to interlit the concavedsurface on the frame and the oitf wardly extending headed projectionsover which the clips slip are provided intermediate the head and basewith a shoulder which holds, or spaces, the clip outwardly away from thewindow .and concrete, hold i ing it in the desired position. Y

In the specific embodiment of the invention which l have chosen toillustrate for the purpose of making a full and complete disclosure, thenumeral 10 indicates a metal window sash formed of an' angle iron havingan inwardly extending leg 11 and outwardly extending leg 12. vA flange13 projects from the leg 11` near its juncture with the leg 12 toprovide an outward abutment for the window glass 14 which is secured inposition by suitable cement or other material 15. Between the outer faceof the iange 13 and the inner edge of the leg 12 a concaved verticallyextending surface 16 is provided and it is against this verticallyextending concaved surface that I attach `my support.

The support comprises a verticaly extending base 17 having its rearsurface convexed, as at 18. to intert with the concaved surface 15 ofthe window sash. From the outer convex surface 19 two spaced apartheaded projections 20 extend for engagement with the window washersslotted clip, indicated in general by the numeral 21. These projections20 have heads 22 formed on their outer ends and anges or shoulders 23intermediate the head and base, forming annular grooves at 24 betweenthe heads 22 and flanges 23, in which the slotted clip 21 slides. Thehead 23 therefore serves to space the clip outwardly away from thesupports to prevent any possible side movement of the clip such as mightcause its engagement with the window 14. This arrangement of theshoulder adjacent the head on the end of the projection also serves toguide the clip as it is slid over the projection and holds it firmly inthe position shown in Fig. 2, preventing wabbling or side movement.

The base may be secured to the sash in any. suitable manner, as forexample, by the screws 25 taking through countersunk holes in the baseinto threaded holes in the sash. The ends of the screws may be headedover, as at 26, for additional security.

Whereas I have illustrated and described but a single embodiment of myinvention, it will be evident to those skilled in the art that variouschanges or modifications may be made without departing from the spiritof the invention or the scope of the appended claims.

Having described my invention, what I claim is 1. A device forengagement with a window washers slotted safety clip and for attachmentto a window frame between ag'ularly disposed walls, comprising anelongated base 17, two spaced-apart headed pro: jections, 20, eachprojection provided with spaced apart heads, 22 and 23, to provide aspace 24 to receive the clip 21, the inner head, 23, being spaced apartfrom the base 17 a distance sucient to permit the clip to clear the walland glass when the base is located at the junction of angularly relatedwalls.

2. In combination with a metal window sash having an abutment to receivethe window glass and a vertically extending concaved surface on theoutside of said abutment a supporting means having an elonated base partwith its rear or under surace convex to fit said concave surface, saidsupporting means havin a plurality of spaced apart headed roJections,each projection being provides with an outer head and an intermediatehead spaced apart to receive a window washers slotted clip, saidintermediate head being spaced from said support, said heads extendingat an' angle with reference to the sides of the angle between saidwindow glass and frame, whereby the clip is held away from the glass andframe to prevent enga ement therewith.

In testimony whereo I hereunto set my hand.
